The embodiments below are for describing the present application but are not used to limit the scope of the present application.

A person skilled in the art may understand that the terms such as “first” and “second” in the present application are merely for distinguishing different steps, devices or modules, and do not represent any special technical meanings, and also do not represent necessary logic order among the steps, devices or modules.

FIG. 1 is a flowchart of a method for controlling task migration provided in an embodiment of the present application. The method for controlling task migration provided in the present application may be executed by an apparatus for controlling task migration. A device presentation form of the apparatus for controlling task migration is not limited. For example, the apparatus for controlling task migration may be an independent electronic device. Alternatively, the apparatus for controlling task migration may be integrated as a functional module in an electronic device, which is not limited in the embodiment of the present application. Specifically, as shown in FIG. 1, the method for controlling task migration provided in the embodiment of the present application comprises:

Step S101: Determine available device difference information of a first device set and a second device set, the first device set comprising one or more user previously-available devices, and the second device set comprising one or more user currently-available devices.

The “previous” and “current” are for distinguishing two determining moments of different timing. The “available” represents whether a user device is available to a user at a determining moment. A user device available to a user at a first determining moment is the user previously-available device, and the first device set comprises one or more user previously-available devices. A user device available to a user at a second determining moment is the user currently-available device, and the second device set comprises one or more user currently-available devices. For the types, the user device, the user previously-available device, and the user currently-available device in the embodiments of the present application may be, but are not limited to, a mobile phone, a computer, a notebook computer, a tablet computer, smart glasses, a smart watch, a smart wristband, a smart television, a smart loudspeaker, and the like.

Due to influence by one or more factors such as a change of a user position and a change of a user device, the first device set and the second device set may be partially different or completely different. The available device difference information comprises: information of at least one user previously-available device that is switched from a user previously available state to a user currently-unavailable state in the first device set. In other words, the first device set comprises a user device but the second device set does not comprise the user device; therefore, the user device is switched from a user previously available state to a user currently-unavailable state, and the available device difference information comprises information of the user device.

For example, the first device set comprises 3 user previously-available devices, which are separately marked as UD1, UD2, and UD3. The second device set comprises 1 user currently-available device, which is marked as UD3. In this case, the available device difference information of the first device set from the second device set involves UD1 and UD2.

Step S102: Determine at least one user previously-available device as a source device according to the available device difference information.

It is determined which user device or which user devices in the first device set are switched from a previously available state to a current unavailable state, and therefore one or more user previously-available devices may be determined as the source devices. For example, the available device difference information of the first device set from the second device set is UD1 and UD2, and UD1 or UD2 or UD1 and UD2 may be determined as the source devices.

Step S103: Migrate at least one task currently running on at least one source device to at least one user currently-available device.

One or more source devices may be determined. One or more tasks may currently run on each source device. One or more tasks may be migrated. A task may be migrated to one or more user current available devices. For example, video playback task A and instant messaging task B currently running on UD1 are switched on UD3.

In the method for controlling task migration provided in the embodiment of the present application, one or more user previously-available devices that are switched from a previously available state to a currently unavailable state may be intelligently found, at least one of the one or more user previously-available devices is determined as a source device, and at least one task currently running on at least one source device is migrated to at least one user currently-available device. Therefore, without interrupting a user's use of a task being migrated, convenience of use by a user is improved, and user experience is improved.

In the technical solution provided in the embodiments of the present application, the method for determining available device difference information of a first device set and a second device set may be selected according to an actual request or need, so that an example embodiment is very flexible.

In an example embodiment of determining the user device difference information, the apparatus for controlling task migration may acquire user previous position information, user current position information, and user device position information; determine the first device set according to the user previous position information and the user device position information; determine the second device set according to the user current position information and the user device position information; and determine the available device difference information according to the first device set and the second device set. An optional scenario is, for example, that a user moves from position a to position b. The apparatus for controlling task migration may determine user available devices within a certain range of position a (that is, the first device set) and user available devices within a certain range of position b (that is, the second device set) by combining the user position information and the user device position information, and determine a difference of the user available devices comprised in the two ranges (that is, the available device difference information). The user position information and the user device position information may be determined by using, but not limited to, a positioning technology such as GPS. In the solution, a change of a user device available to a user when the user is at a different position may be intelligently discovered (that is, no manual involvement is required in a discovery process) according to position information.

In another example embodiment of determining the user device difference information, the apparatus for controlling task migration may determine the first device set and the second device set through near-field detection; and determine the available device difference information according to the first device set and the second device set. The near-field detection may be implemented by using one or more near-field detection technologies as follows: infrared, visible light communication, WiFi, Zigbee, Bluetooth, and the like. In the solution, it may be intelligently discovered, through near-field detection, which user devices are the user previously-available devices (that is, the first device set), which user devices are the user currently-available devices (that is, the second device set), and the available device difference information between the user previously-available devices and the user currently-available devices (that is, it is determined which user devices are switched from a previously available state to a current unavailable state).

In still another example embodiment of determining the user device difference information, the apparatus for controlling task migration may determine the first device set and the second device set through human bioelectricity detection; and determine the available device difference information according to the first device set and the second device set. The optional scenario is, for example, that the apparatus for controlling task migration may detect human bioelectricity information of a user by using, but not limited to, a sensor, and determine, according to the detected human bioelectricity information, a wearing condition of a wearable device (for example, smart glasses, and a smart watch) of a user. If it is determined that a user is wearing the wearable device at a first detection moment, the wearable device is the user previously-available device. If it is determined that the user is still wearing the wearable device at a second detection moment, the wearable device is the user currently-available device. If it is determined that the user does not wear the wearable device at the second detection moment, the wearable device is not the user currently-available device. In the solution, a change of a user device available to a user may be intelligently discovered by using a technology of human bioelectricity detection.

The foregoing example embodiment of determining the user device difference information may be separately implemented, or may also be implemented in combination. For example, at least two of position information, a near-field detection technology, and a human bioelectricity detection technology may be combined to separately determine the first device set, the second device set, and the available device difference information. The example embodiment is no longer elaborated here in the embodiment of the present application.

After the available device difference information is determined, it may be further determined accordingly that one or more user previous available devices are the source devices, and at least one task currently running on at least one source device is migrated to at least one user currently-available device. Optionally, at least one task to be migrated may be determined according to at least one task currently running on at least one source device; at least one user currently-available device is determined as a destination device; and at least one task to be migrated is migrated to at least one destination device. There may be one or more source devices, one or more tasks may currently run on each source device, there may be one or more tasks that are to be migrated (that is, tasks to be migrated) on each source device, and each task to be migrated may be migrated to one or more destination devices. Therefore, migration of at least one task between a single source device and a single destination device, migration of at least one task between a single source device and multiple destination devices, or migration of at least one task between multiple source devices and multiple destination devices may be implemented, to cause migration of a task to be more natural and smart, so that a variety of application demands of a user may be better met. Further, a mapping relationship between at least one task to be migrated and at least one destination device may be determined; and a corresponding task to be migrated is migrated to a corresponding destination device according to the mapping relationship. For example, a task to be migrated may be migrated to one or more destination devices, or, some tasks to be migrated are migrated to a same destination device. In the solution, task migration is controlled on the basis of the mapping relationship, thereby improving efficiency of controlling task migration.

In the technical solution provided in the embodiments of the present application, the manner of determining a destination device may be determined according to an actual request or need, which is not limited in the embodiment of the present application.

In an example embodiment of determining the destination device, matching information between at least one source device and one or more user currently-available devices may be determined; and at least one user currently-available device of which the matching information meets a predetermined condition is determined as the destination device. The matching information may be determined according to at least one of, but not limited to, a device type, a model, and device capability information. For example, respective device capability information of at least one source device and one or more user currently-available devices may be acquired; and the matching information is determined according to the acquired device capability information. Specifically, device capability information of the source device and device capability information of each user currently-available device may be acquired, and device capability information of any device may comprise, but is not limited to, at least one piece of information as follows: a performance parameter of a human-machine interaction member of a device, a performance parameter of a computation member of a device, a performance parameter of a display member of a device, a performance parameter of a transmission member of a device, battery durability information of a device, a performance parameter of a sensing sensor of a device, and the like. These performance parameters may be separately considered to determine a matching degree, or may also be considered in combination (for example, respective weight values are determined for different performance parameters) to determine a matching degree. The determined matching degree is compared with a preset condition. For example, the user currently-available device of which a determined matching degree is greater than a predetermined threshold is the destination device. In the solution, the user currently-available device that matches the source device well may be determined as the destination device, so as to facilitate subsequent successful migration of a task without interrupting use by a user.

In another example embodiment of determining the destination device, application resource information used for running at least one task to be migrated may be acquired; respective device capability information of one or more user currently-available devices is acquired; and at least one user currently-available device is determined as the destination device according to the application resource information and the device capability information. The application resource information may comprise, but is not limited to, information of an application related resource, and a system resource (for example, memory, and an I/O device) used for running of an application. The device capability information of the user currently-available device is compared with resource information for running of the task to be migrated, and the user currently-available device that is suitable for successful running of the task to be migrated may be determined as the destination device, so as to facilitate subsequent successful migration of the task without interrupting use by a user.

After the destination device is determined, at least one task to be migrated may be migrated to at least one destination device.

In a case where there are multiple tasks to be migrated, distinguished control of task migration may be performed to improve efficiency of task migration and convenience of use by a user. For example, task migration priority level information of multiple tasks to be migrated may be determined; and a corresponding task to be migrated is migrated to at least one destination device according to the task migration priority level information. Different tasks may have different importance and meanings for a user. A priority level of each task to be migrated may be determined according to an actual condition, and a task to be migrated having a relatively high priority level is migrated preferentially, to cause an application resource of the destination device to preferentially meet running of these tasks, so that efficiency of task migration is improved and demands of a user may be better met.

The method for determining priority levels of different tasks to be migrated may be determined according to an actual request or need, and is not limited in the embodiment of the present application. For example, the task migration priority level information may be determined according to the type of the task. Alternatively, for another example, respective user usage information of multiple tasks to be migrated may be acquired; and the task migration priority level information of the multiple tasks to be migrated is determined according to the acquired user usage information. The user usage information may comprise, but is not limited to, information such as the time and frequency of running of a task. In the solution, task migration priority levels of different tasks to be migrated are determined according to the user usage information, so as to preferentially migrate a task with which a user is concerned more, thereby better meeting demands of actual applications of the user.

In a case of multiple destination devices, distinguished control of task migration may also be performed to improve convenience of use by a user. For example, device priority level information of multiple destination devices may be determined; and at least one task to be migrated is migrated to a corresponding destination device according to the device priority level information. Different destination devices may have different use frequencies and use convenience for a user. A priority level of each destination device may be determined according to an actual condition, and the task to be migrated is preferentially migrated to a destination device having a relatively high priority level. For example, a smart phone has a higher use frequency for a user as compared with other user devices such as a smart television and is also often carried along, and therefore the task to be migrated may be preferentially switched to the smart phone to improve convenience of use by the user.

In the embodiment of the present application, migrating a task to a destination device may be determined according to an actual request or need, and is not limited in the embodiment of the present application. For example, the apparatus for controlling task migration may acquire execution state information of the task to be migrated, and send the execution state information to the destination device. The destination device determines an application resource that may present the execution state information, and creates a task in a multi-task list currently running in an operating system of the destination device, so that the migrated task may continue running by using the new task created on the destination device. In this case, content corresponding to the execution state information may be accessed on the destination device. Therefore, without interrupting use by the user, convenience of use by a user is improved and user experience is improved.

A person skilled in the art may understand that in any method above in the example embodiment of the present application, the sequence numbers of the steps do not mean an execution order, where the execution order of the steps should be determined by the functions and internal logic of the steps, and should not constitute any limitation on the example embodiments of the present application.
